How Much Physics Should a Neural Network Know? Thermodynamics‐Informed Neural Networks for Rock Constitutive Modeling With Epistemic Uncertainty

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Machine learning offers a flexible route to constitutive modeling, with two emergent questions for geoscience applications: what level of thermodynamic constraint should be embedded in the network architecture, and how should predictive uncertainty be quantified when extrapolating from laboratory to field conditions? We address both challenges

The Material Basis of 18th‐Century Meissen Porcelain

Archaeometry, Volume 68, Issue 5, Page 908-918, October 2026.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Anisotropic characteristics and creep model for thin-layered rock under true triaxial compression

Journal of Rock Mechanics and Geotechnical Engineering
The failure phenomenon of thin-layered rock tunnels not only exhibits asymmetric spatial characteristics, but also significant time-dependent characteristics under high in-situ stress, which is attributed to the time-dependent fracture of thin-layered ...

A method to determine strength parameters by triaxial testing and 3D rock failure models

Journal of Rock Mechanics and Geotechnical Engineering
Estimating the strength parameters of a chosen rock failure criterion is crucial for rational stability analyses. However, the grid search algorithm applied to true triaxial test data presents challenges that hinder its widespread adoption.

Evolution of mechanical parameters of Shuangjiangkou granite under different loading cycles and stress paths

Journal of Rock Mechanics and Geotechnical Engineering
Surrounding rocks at different locations are generally subjected to different stress paths during the process of deep hard rock excavation. In this study, to reveal the mechanical parameters of deep surrounding rock under different stress paths, a new ...

Probability prediction of true‐triaxial compressive strength of intact rocks based on the improved PSO‐RVM model

Deep Underground Science and Engineering
In deep underground engineering design, the true‐triaxial compressive strength of intact rocks is a critical evaluation index. Traditional methods for acquiring true‐triaxial strength data are hampered by labor‐intensive manual operations.
